In the present study, the distribution and abundance of Ichtyoplankton was made in Kodiakkaari and
Arukattuthurai of Vedaranyam coast, south east coast of India. Both the station occupies an important place
in the fishing area of Tamilnadu. Monthly sampling of Icthyoplankton were made for one year (September 2006
to August 2007) covering a stretch of 30 km. The Ichthyoplankton at both station composed of family
Scombridae, Mugilidae, Teraponidae, Lujanidae, Pomadasydae, Scianidae, Clupeidae, Carangidae, Latidae,
Sphyraenidae, Engraulidae, Leiognathidae, Tetradentidae and Chirocentridae. A maximum density (76/10m3)
of fin fish larvae was observed during summer followed by a secondary peak in postmonsoon season. In both
the stations Teraponidae showed the major larval composition (15.27 and 14.05) and Tetraodontidae
encountered lowest composition (3.05). Seasonal wise composition of Icthyoplankton refers that the abundance
was maximum in manosoon (Pomacentridae 32.56 %) and minimum (Tetraodontidae 0.99%) in summer.
Physicochemical parameters such as Temperature, pH, Salinity, Dissolved oxygen and Rainfall were also
recorded from the stations in relation to the distribution and abundance of Icthyoplankton.
